Abstract

The invention provides a cable-stayed bridge steel beam segment swing shifting device and a hoisting method, the cable-stayed bridge steel beam segment swing shifting device comprises a first hoisting swing shifting system and a second hoisting swing shifting system, the first hoisting swing shifting system is provided with a first hoisting power unit and a first swing shifting unit, and the second hoisting swing shifting system is provided with a second hoisting power unit and a second swing shifting unit. And through cooperation of the first hoisting and swinging system and the second hoisting and swinging system, efficient installation of the steel beam is completed. The construction efficiency is high, the manufacturing cost is low, installation is quick, the construction period can be shortened while construction safety is guaranteed, and the cost input of hoisting equipment is reduced.

Description

technical field [0001] The invention relates to the construction field of hoisting steel girder segments of cable-stayed bridges, in particular to a method for swinging, moving, and hoisting steel girder segments of cable-stayed bridges. Background technique [0002] Cable-stayed bridges are widely used due to their economical cost, good durability and low maintenance cost. Some superimposed steel girder sections have heavy hoisting weight, and the installation location exceeds the performance coverage area of ​​the hoisting equipment. It is difficult to use super-large equipment in the complex terrain of the mountainous area, which increases the difficulty of construction. [0003] In traditional construction, it is usually solved by increasing the performance of lifting equipment. The problems of this method are: the requirement for the bearing capacity of the foundation is increased, the design difficulty of the wall attached to the main tower is increased, and the const...
